To alliu'homz t-mdy comm.-

Be-it known that LHENRY F. SOHOEN- FIELD, a citizen of the United States, residing at' Roseburg, in the county of Douglas and State of Ore on, have invented certain new and useful mprovernents in Trusses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

The object of my invention is the pro-' vision of an elastic truss which shall be simple in construction, cheap in first cost and durable, and which when in use by a person suffering from rupture will maintain a proper position under all conditions, whatever may be the relative positions of the body and limbs as the result of the movement of the same. i V The main fault or imperfection of trusses now .in useis that the belt must be drawn quite tight to hold the pad in place, which causes pain, distress and discomfort to the wearer, and even then the pad frequently becomes displaced under bodily movement. My truss is designed to be worn relatively loose and yet hold the pad in place, the belt being elastic and slidable relative to the pad and the plate spring, which latter yieldingly presses the pad against the body, so that the pad and plate spring are not displaced when the belt moves in consonance with the expansion and contraction of the muscles of the-body.

The invention consists in certain novel ties of construction and combinations of parts as herein set forth and claimed.

The accompanying drawing illustrates an example of the embodiment of the invention, the parts being constructed and combined according to the best mode of procedure I I have so far devised for the purpose.

- Figure 1 is a perspective view of the truss about as it appears when in use and secured in position on thebody, the'elastic belt and spring being under slight tension.

Fig. 2 is a perspective view of the truss when the belt and spring are not under tension, and detached from the body.

Fig. 3 is a view showing the pad and plate spring in longitudinal section and the edge of the belt in elevation.

Referring o the figures of the drawing, the numeral 1' designates" a pad of wood-or other suitable material having a rounded'or curved surface 2, a plane surface3, a slot 4 and a recess 5. To the plane surface of the pad is secured by a set-screw 6 a concavo-convex plate spring 7 provided at each end with a perforated clip 8, said clips being bent to? shape and secured to the ends of the spring or formed-integral therewith. as desired. About the clips may be secured cushioning pads, preferably secured to the sprmg or clips. One clip is shown with such a pad 9 having a hole or passage therethrough for the belt and secured to the clip by threads 10 or other means. I

Through the slot 4.- and the openings in the clips and cushioning pad '9 is loosely passed an elastic belt 11 having a buckle 12 at one end and the other end provided with a series of holes 13 to receive the tongue of the buckle; One end of an anchoring or holding elastic strap 14 is secured in the recess or slot 5 of the pad by a pin or rivet 15 and the other end of the strap is adapted to engage a buckle 16 on a band 17-.slidable upon the belt, all as shown. I

Fig. 1 shows the positions of the several 7 parts of the truss when secured to the body and in use. The elastic belt and the elastic anchoring or holding strap are slightly under tension and the plate spring is also under tension and the ends bent backwardly from their normal position, as shown. The

I elastic belt and the contour of the body prevents the pad from moving downwardly and the holding strap prevents it moving upwardly. The elastic belt passes loosely through the pad and the clips at the ends of the plate spring so it can move relative to the pad and plate spring in part or as a whole when the muscles of the body are displaced from normal positions or a position of rest in walking or bending the body forwardly or backwardly or from side to side and without displacing the pad, as is obvious from the construction and combination of parts of the truss as shown and described.

It is to be understood that modifications and changes may be made in the embodiment of the invention as shown without constituting a substantial departure from the principle of the invention.
